SPRA Y-PUM P.

SPECIFICATION forming part of Letters Patent No. 637,213, dated November14, 1899.

Application filed February 23, 1899. Serial No. 706,532. (No model.)

To all whom it may concern:

Be it known that I, ISAAC W. NUMAN, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Spray-Pumps; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the figures of referencemarked thereon, in which Figure 1 is a side elevation of a pumpcontaining my improvements. Fig. 2 is a vertical longitudinal section.Fig. 3 is a view showing the top or upper end of the inner cylinder orbarrel. Fig. 4 is a view showing the top or upper end of the pump properin vertical section, also showing the stirrup or foot-piece connectedthereto. Fig. 5 is a View showing the lower valve, also showing theconnecting-flange. Fig. 6 is a View showing portions of the pump-barrelsand illustrating the position of the valve leading from the workingbarrel to the air-chamber. Figs. 7 and 8 are detached views of thespray-nozzles.

The present invention has relation to spraypumps; and it consists in thenovel arrangement hereinafter described and particularly pointed out inthe claims.

Similar numbers of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, 1 represents the outer cylinder, whichcylinder is located around the working barrel 2, said parts beinglocated and arranged substantially as shown in the drawings.

For the purpose of providing an air-chamber between the cylinder 1 andthe barrel 2 the top or upper end of the cylinder 1 is closed by meansof the collar or cap 3, which cap or collar is arranged substantially asshown in the drawings. The collar or cap 3 also provides a means forholding the top or upper portion of the barrel 2 in proper relativeposition. The bottom or lower end of the cylinder 1 is provided with thestrengtheningband t and the inlet-apertures 5, said parts being locatedand arranged substantially as shown in the drawings.

The bottom or lower end of the barrel 2 is held in proper relativeposition by means of the disk 6, which disk is provided with the cup 7,and into which cup the bottom or lower end of the barrel 2 is seatedsubstantially as illustrated in Fig. 2. a

At the bottom or lower end of the barrel 2 is located the valve 8, whichvalve is provided at its bottom or lower end with the rubber disk 9; butit will be understood that any other suitable material may be used inthe manufacture of said disk 9, as the only object to be accomplished isto provide a perfect working valve.

For the purpose of connecting the disk 9 and the valve together thescrew 10 is provided, which screw is passed through the opening 11, asillustrated in Figs. 2 and 5, said screw being provided with a head oreye, so as to prevent the valve 8 from being carried upward during theupward stroke of the plunger 12 except a sufficient distance to allowwater to pass the valve during the upward stroke of the plunger.

The delivery-tube 13 is located substan tially as shown in Fig. 2, and,as shown, it extends to within a short distance of the bottom of theair-chamber 14 and is extended upward and beyond the upper end of thebarrel 1, and its top or upper end is turned at an angle, so as toprovide a means of easily attaching the hose 15.

For the purpose of providing an escape for any water that may find itsway above the plunger 12 the drip 15 is provided, which drip is open atits bottom or lower end and, as shown, it is connected to the barrel 2and the cylinder 1, and the passage 16 being provided between said dripand barrel 2, thereby allowing the water to find its way through thedrip 15.

The plunger-rod 17 is constructed in the ordinary manner, and its top orupper end is provided with the ordinary handle 18, which may be of anydesired form.

The plunger 17 is held in proper relative position by means of thestopper 19, which stopper is seated into the top or upper end of thebarrel 2, by which arrangement the top or upper end of the barrel isproperly closed.

Forlhe purpose of providing for the expan sion and contraction of thestopper 19 by reason of its contact with Water and then becoming driedthe top or upper end of the barrel 2 is provided with the slit 20, whichallows the barrel to expand with the stopper, which stopper ispreferably made of wood. For the purpose of closing the barrel 2 at itstop or upper end as the stopper contracts the springring 21 is providedand is connected in any convenient and well-known manner to the barrel2, said spring-ring being so tempered that it will hold the stopper atall times and under all circumstances.

For the purpose of holding the pump proper in an operating position thestirrup or footpiece 22 is provided, which stirrup or footpiece ispreferably formed of a single piece of material, its top or upper endbeing bent over and connected a short distance below the top proper, asillustrated in Figs. 1 and 4, by which arrangement the foot-piece properis held a short distance away from the pump proper, so that said stirrupor foot-piece can be placed upon the outside of a pail or other vesselinto which the pump is to be placed.

For the purpose of providing a means for allowing the water to pass fromthe barrel 2 into the air-chamber and enter the deliverytube 13 thevalve 23 is provided and is located at the bottom or lower portion ofthe pump proper. The valve 23 consists of a ball and is inclosed in theconical cup 21L, which cup is attached to the barrel 2. For the purposeof properly inelosing the valve 23 and at the same time allowing for themovements of the valve the chamber 24 is provided,which chamber is shownpartially broken away in Fig. 6. It will be understood that a cap, suchas 25, should cover the chamber 24, which cap is held in place by properscrew-threads and is to be removed only when it is desired to drain thepump.

For the purpose of preventing the ballvalve 23 from becomingaccidentally displaced during the time the cap is removed a bar, such as26, extends across the outer end of the chamber2-l. For the purpose ofprovidinga pump that can be used for different purposes the attached tothe nozzle 27.

outer end of the nozzle 27 is provided with the removable tips 28, 29,and 30, which tips are connected together by means of their disks 31,which disks are formed of such a size that the tips will be held asufiicient distance apart to allow any one of said tips to be Each tipis pro vided with a different-shaped aperture, by which arrangement saidtips may be used for different purposes, such as throwing a solid streamor spraying.

It will be understood that by connecting the different tips together andarranging them as shown the tips not in use will be out of the way andat the same time can be easily connected after the one in use has beendetached, it being understood that the screwthreaded portions of thedifferent tips are to be of the same size, so that they will beinterchangeable.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination of the cylinder 1, a barrellocated within thecylinder, a plunger located within the barrel and a valve located belowthe plunger, said barrel provided with a drip at its upper end and aspring-ring located around the barrel and the stopper 19, substantiallyas and for the purpose specified.

2. The combination of the cylinder 1 and the barrel 2 located within thecylinder and provided with a plunger, the disk 6 provided with the cup7, the valve 8 located in the bottom or lower end of the barrel the disk9 and the screw 10 extended through the opening 11 formed in the disk 6,substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

ISAAC WV. NUMAN. Witnesses:
